My wife and I are expecting another child and wanted to upsize her Honda Accord to something more spacious. As part of that I needed to trade in my '16 bone stock Silverado 2500 to downsize my truck payment. Before: After: I did just that, downsized, and got myself in an '06 F350. It has the 6.0L that is bulletproof. I think. It has a disconnected banks 6 gun tuner and a disconnected SCT tuner in the glovebox. I'm new to any diesel mods, and as you can see this thing has some mods. How do I make sure I'm "bulletproof," and how do I run some different tunes? Do I run a risk of wiping the stock program? Any pointers at all for a pre-DEF diesel new owner?
